No

zbarcam starts really slowly on windows, it takes about 10 seconds to test all the possible video formats. If user knows the format, he could speed things up supplying the format on command line. A --vfw-format switch? I'm ready to do it.

    Yes, it takes forever to test the formats because, amazingly, VfW provides no interface to query them. Again, DIrectShow has much better support for all of this...

    btw- if you do want to waste your time on VfW, special windows flags are not a good option, just use the existing --infmt flag.

    I'm trying to make 0.11 version ready to go. I guess I have to make vfw usable then. So I'll have to put --infmt into manual as well.
